What Is a Captive Generating Plant in India? Meaning, Law and Compliance

A captive generating plant (CGP) is a power plant set up by a person to generate electricity primarily for that person’s own use, as defined in Section 2(8) of the Electricity Act, 2003. To qualify, captive users must hold at least 26% ownership and consume at least 51% of annual generation, under Rule 3 of the Electricity Rules, 2005 (as amended in 2026).

A captive generating plant is one of the most commercially important structures in Indian power. It is how large industrial and commercial consumers generate their own electricity, increasingly from solar or wind, to avoid the surcharges that ordinary grid consumers are lawfully required to pay.

Key terms:

• A captive generating plant is a plant set up primarily for the owner’s own use (Section 2(8), Electricity Act, 2003).
• “Captive generating plant” and “captive power plant” mean the same thing; the statute uses the former.
• A captive user is the end user of the power, a company, body corporate, cooperative society, or an association of persons, not just an individual.
• The 26/51 test (Rule 3): captive users must hold ≥26% ownership and consume ≥51% of annual generation.
• No generation license is needed (Section 9); captive open-access self-use is exempt from cross-subsidy and additional surcharge (Section 42(2)).
• The Electricity (Amendment) Rules, 2026 redefined the captive user, recognised energy-storage consumption, treated SPVs as associations of persons, and created a new NLDC / State nodal-agency verification regime.

What is a captive generating plant?

A captive generating plant is a power plant built mainly so the owner can use the electricity itself instead of buying all of its power from a distribution company. That is the legal idea in Section 2(8) of the Electricity Act, 2003, which defines a captive generating plant as a power plant set up by any person to generate electricity primarily for his own use. In India, that “person” can be a company, a body corporate, or a wider association of persons and not just an individual.

Many people believe that the captive power plant means it can only be a factory-owned generator inside an industrial campus. Legally, it is wider: a captive plant can be a single-user structure, or a shared structure built for several qualifying users acting together. While interpreting Section 2(8), the Supreme Court explained that the statute recognises both a single-user concept and a group-user concept and the present Rule 3 now expressly treats a special purpose vehicle (SPV) as an association of persons for captive purposes.

Where the law sits: Section 2(8) Electricity Act and beyond

These three provisions together explain captive generating plant. Section 2(8), Section 9 and Rule 3 of the Electricity Rules, 2005.

• Section 2(8) supplies the definition of the “primarily for own use” test.
• Section 9 supplies the rights: a person may construct, maintain or operate a captive generating plant and dedicated transmission lines, with a right to open access to carry that power to the point of use, subject to transmission availability.
• Rule 3 supplies the qualifying test — the 26% / 51% thresholds explained below.

Section 9 is also the source of the much-discussed position that captive power needs no license. The section expressly provides that no license is required to supply electricity generated from a captive generating plant to any licensee in accordance with the Act, or to any consumer subject to the regulations under Section 42(2). Reinforcing this, Section 7 confirms that a generating company may establish, operate and maintain a generating station without a license so long as it meets grid-connectivity standards.

Who qualifies as a captive user?

The current rules use the term captive user, which is more precise than the looser market shorthand “captive consumer.” Under the substituted Rule 3, a captive user is the end user of the electricity generated in a captive generating plant. The rule now expressly allows that electricity to be consumed either directly or through an energy storage system that stores energy generated from the captive plant.

The 2026 framework also expands the corporate meaning of who qualifies as a captive user. Where the captive user is a company, the rule deems it to include its subsidiary or subsidiaries, its holding company, and any other subsidiary of that holding company. All of these are collectively treated as a single captive user.

“Ownership” is correspondingly broadened to recognize voting equity or control held directly or through those group entities. For industrial groups operating through affiliates, holding companies or SPVs, this is one of the most valuable clarifications in current law, because it lets a group aggregate holdings and plan consumption across entities.

The 26% ownership and 51% consumption rule

The shorthand practitioners use is the 26/51 test. A power plant will not qualify as a captive generating plant unless at least 26% of its ownership is held by the captive user or users, and at least 51% of the aggregate electricity generated in the plant during the financial year is consumed for captive use. These two thresholds are the compliance spine of Rule 3, examined in our explainer on the 26% / 51% twin test for captive power.

For single-user structures, the logic is simple: if a company owns and uses the plant mainly for its own needs and the Rule 3 thresholds are met, the project stays captive. For group captive structures the logic is more technical, because ownership and consumption are measured collectively and, in some cases, proportionately.

The Supreme Court’s 2023 judgement in Dakshin Gujarat Vij Company Ltd. v. Gayatri Shakti Paper and Board Ltd. is essential here. The Court held that the ownership and consumption tests are linked and rejected the argument that the 26% threshold need only be satisfied at year-end, the minimum ownership must be maintained throughout the year.

It also explained the proportionality principle, the qualifying ratio is 51 divided by 26, or roughly 1.96, so the owner of every 1% shareholding should consume a minimum of about 1.96% of the electricity generated, within the permitted variation. Although the 2026 Rules redrafted Rule 3, that reasoning still explains why ownership and consumption have always been treated as linked tests rather than separate checkboxes.

Group captive, AoP and SPV structures

Many modern captive projects are not simple one-company, behind-the-meter arrangements. They are structured as group captive projects, commonly through an association of persons (AoP) or an SPV. The 2026 Rules now state expressly that an SPV shall be treated as an association of persons for captive purposes, since SPVs are widely used to own and operate the project assets while consumption happens across several participating users.

For a plant set up by an AoP, the 2026 Rules say the ownership and consumption conditions are satisfied collectively by all captive users, and aggregate consumption by all such users is considered when verifying compliance. The rules then layer in a proportionate-consumption concept for each individual user, with important exceptions: a captive user holding not less than 26% ownership is not subject to the individual proportionate-consumption cap, and the rules provide for weighted-average shareholding where ownership changes during the year.

Tribunals have worked to keep the test tied to the actual plant. In a 2024 decision, the Appellate Tribunal for Electricity (APTEL) emphasized that the 51% consumption test is power-plant-centric; you cannot aggregate consumption across multiple plants to rescue captive status for one plant that does not independently qualify. Each plant, or the identified captive unit, must meet the conditions applicable to it.

What happens if a captive plant fails compliance?

A captive plant is only as useful as its annual compliance. Rule 3 makes the consequence clear: if the captive users do not meet the minimum captive-consumption requirement during the financial year, the entire electricity generated by the plant is treated as supply by a generating company, and cross-subsidy surcharge and additional surcharge become leviable. In AoP structures, excess consumption by an individual user beyond its eligible proportionate entitlement is likewise treated as ordinary supply for that excess.

The 2026 amendment also rewired verification:

• Intra-State captive consumption — verified by the State-designated nodal agency.
• Inter-State captive consumption — verified by the National Load Despatch Centre (NLDC) under its approved procedure.
• Appeals — to a Grievance Redressal Committee constituted by the appropriate government.
• Transition — inter-State verification for electricity consumed up to FY 2025-26 stays with the Central Electricity Authority; FY 2026-27 onward shifts to the NLDC (inter-State) and State nodal agencies (intra-State).

Pending verification, the rules say CSS and AS should not be levied if the captive users furnish the prescribed declaration. But this is not a permanent shield: if the plant later fails verification for that year, the charges become payable along with carrying cost. That makes annual ownership tracking, generation metering, consumption mapping and clean documentation central to any serious captive strategy.

Conclusion

So, what is a captive generating plant? In India, it is not simply “a plant you own.” It is a power project that fits a specific statutory idea under Section 2(8), enjoys special rights under Section 9, and continues to qualify only while it passes the ownership-and-consumption tests in Rule 3. Designed properly and monitored annually, captive status can unlock open-access self-use without the ordinary surcharge burden. Designed or monitored poorly, the project can lose captive treatment and become, in law, ordinary supply from a generating company.

Captive projects are highly fact-sensitive: surcharge exposure often turns on annual data, ownership movement during the year, the units identified as captive, and the verification process. The definition is settled; the advice that flows from it depends on the facts.
